Cams and trim potentiometers functions

Cam 1:

130° 

Limits rotation towards maximum

Cam 2:

0° 

Limits rotation towards minimum, air damper closed on stand by

Cam 3:

20° 

Limits ignition position

Cams 4 - 5 - 6 - 7 - 8

: not used

Trim potentiometer MAX

Limits maximum modulation. It must be set near the stroke end
(cam 1) to exploit as far as possible the variable profile cam.

Trim potentiometer MIN

Limits minimum modulation. It must be set near the stroke end
(cam 2) to exploit as far as possible the variable profile cam.

Trim potentiometer POS

Limits an intermediate operating position between MAX and MIN,
supplying power to the “P” terminal in the servomotor (through an
external command). This function cuts out any external signals.

NOTE:
using the slide switch (Fig. 38) to select MAX or MIN, the ser-
vomotor goes into the position for the respective settings of
the MAX and MIN TRIM POTENTIOMETERS.

When the settings are complete, place the slide switch on “

OPE

”

(operate).

Final calibration of the pressure switch

5.5.1

Air pressure switch

Adjust the air pressure switch after having performed all other burn-
er adjustments with the air pressure switch set to the start of the
scale (B).
With the burner operating at min. output, increase adjustment pres-
sure by slowly turning the relative dial clockwise until the burner
locks out.
Then turn the dial anti-clockwise by about 20% of the set point and
repeat burner starting to ensure it is correct.
If the burner locks out again, turn the dial anti-clockwise a little bit
more.
